TYPEWRITING MACHINE.

Application filed February 1, 1921. ,Serial No. 441,523.

T 0 all whom it may concern:

Be it known that I, CHARLES M. HILSEE, a citizen of the United States,residing in Rochester, in the county of Monroe and State of New York,have invented certain new and useful Improvements in TypewritingMachines, of which the'following is a specification.

This invention relates to a device for facilitating the insertion andtyping of several varieties of work-sheets, such as gas or electricbills of the type which require but a single line oftypewriting. In suchcases it is unsatisfactory to insert each work-sheet from the rear,since a great deal of time is consumed in adjusting each sheet to theprinting line.

The present invention is shown as applied to or embodied in an Underwoodstandard typewriting machine, and provides a simple means comprising ashield or auxiliary paper-apron which may be formed from a single pieceof suitable sheet material, as, for example, strong paper. Thisauxiliary paper-apron isprovided with a forwardly and downwardly turnedfront marginal part forming a fold to engage over and cover the sharp orbroken front edge of the usual paper-apron, and thus provide a smooth,unobstructed path for a bill-sheet inserted from the front of themachine. The auxiliary paper-apron overlies the usual or mainpaper-apron, and may be clamped at its rear end to the usual rearpaper-table. The auxiliary paper-apron covers the openings commonlyprovided in the usual paperapron, for the usual feed-rolls, so that afront-inserted work-sheet cannot catch upon or be fouled by the edgesformed by said roll-receiving openings.

Since but a single line is to be typed, it is not necessary to feed thebill-sheet. When another bill-sheet is to be typed, the typed bill-sheetis removed, and another bill-sheet inserted. The operation is extremelysimple and permits rapid and eflicient handling of bill-sheets of thevariety described above.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a perspective view of parts of a typewriter carriage withthe invention applied thereto.

Figure 2 is a vertical section of the mechanism shown in Figure 1.

Figure 3 is a detached view of the auxiliary paper-apron.

A carriage platen-frame 1 is provided with a platen 2, fixed upon ashaft 2*, journaled in the carriage end walls 3, said platen-framehaving a rear paper-table 4 extended to form a paper-apron 5. The apron5 is provided with cut-out openings or notches 6, forming tongues orfingers 7, between which, in the openings 6, front pressure-rolls 8 maybe shifted into and out of engagement with the platen. Similar openingsare provided at the rear of the paperapron for rear pressure-rolls 9. Inthe particular machine shown in the drawings, the

openings for the rear pressure-rolls 9 are tendency to foul and obstructthe frontinsertion of a work-sheet.

To facilitate inserting the work-sheets at the front of the platen,there is provided a shield 10, overlying the usual paper-apron 5 andterminating at its forward end in an out-turned marginal part forming afold 11. The shield 10, which is of flexible material such as strongpaper, or other suitable sheet material, may be inserted from the rearand advanced around the platen until the fold 11 has moved beyond theedge of the main apron 5. The shield 10 is now moved in the oppositedirection until the front fold .11 thereon engages and covers theforward edge of the main apron 5. The fold 11 forms an uninterruptedsmooth rounded edge, to enable a work-sheet to be inserted downwardly atthe front of the platen, between the platen and the shield 10, for thetyping of a single line upon the work-sheet. Also it is to be noted thatthe shield 10 forms an uninterrupted smooth sheet-guiding surface overthe roll-openings 6 in the main paper-apron 5, thus rendering itimpossible for the bottom edge of a worksheet to catch against the edgesformed by the openings 6 should the work-sheet be pushed rearwardlybeyond these openings. The rear end 12 of the shield 10 is detachablyclamped on the paper-table 4 by spring clips 13 fixed on thepaper-table. The feedrolls 8 and 9 may be cast off by a lever 14:.

The operation is as follows: The shield 10 having been installed uponthe machine, as described above, and the feed-rolls remaining cast off,a bill-sheet 15 is inserted from the front of the machine. This isreadily accomplished since the shield 10, where it is bent to form thefold 11, presents a smooth rounded uninterrupted upper edge spaced fromthe platen. The bill-sheet is adjusted, in the usual way, to the lineupon which the items are to be typed. To avoid displacement of thework-sheet during the typing, it may be temporarily clamped in positionby throwing on "the feed-rolls or paper-holders. When the single linehas been typed, the feed-rolls or paper-holders are thrown off, thebill-sheet removed, and a new bill-sheet inserted in the mannerdescribed.

When the shield 10 has been installed upon the machine, it forms apermanent part or feature thereof and remains in its fixed positionthereon, while successive billsheets may be inserted, each to have asingle line typed thereon, and then be withdrawn. Obviously, the shield10 may be removed or detached from the machine to adapt the machine forwriting upon ordinary work sheets inserted from the rear and fed aroundthe platen, and line-spaced in the usual way, by means of the rolls 8and 9, which then become feed-rolls. According to the present invention,the pressure-rolls 8 and 9 are used only as clamping means to press theyieldable shield 10 upwardly to cause the latter to clamp the bill-sheet15 against the platen while a single line is typed thereon.

Variations may be resorted to within the scope of the invention, andportions of the improvements may be used without others.

Iaving this described my invention, I claim:

1. In a typewriting machine, the combi nation with a cylindrical platen,feed-rolls to engage the bottom thereof, feed-roll castoif means, and apaper-apron extending around the bottom of the platen to the deliveryside thereof and provided with feedroll-accommodating openings havingedges on which the bottom edge of a work-sheet thrust downwardly at thefront of the platen, when the feed-rolls are cast off, is liable tocatch, of means for preventing such catching and for thereby convertingsaid machine for front-insertion, comprising a shield sufficientlyflexible to be readily insertable from the rear between the platen andsaid paper-apron, and means to secure said shield on said paper-apronover said openings and with its forward edge covering the forward edgeof the paper-apron.

2. In a typewriting machine, the combination with a cylindrical platenand a paperapron extending around the bottom of the platen to thedelivery side thereof and provided with feed-roll-accommodating openingsextending to the front edge and form ing fingers therebetween, therebyrendering it liable for the bottom edge of a work-sheet, thrustdownwardly at the delivery side of the platen, to catch on said fingers,of means for converting the machine for front-insertion and therebypreventing such catching, comprising a shield readily insertable fromthe rear between said platen and paperapron to cover said openings, andhaving an outwardly-turned fold at its forward edge to be drawnrearwardly over the forward ends of said fingers to form a smoothforward edge, and means to engage the rear end of said shield and detainit in fixed position relative to the paper-apron.

In a typewritingv machine, a revoluble platen, feed-rolls to run on thebottom of the platen, feed-roll cast-off means, and a rear paper-tableextending around the bottom of the platen to the delivery side thereofand comprising fingers at its forward edge with feed-roll-accommodatingopenings therebetween, thereby rendering it liable for the bottom edgeof a work-sheet, thrust downwardly at the front of the platen, to catchon the papertable, and means for converting the machine forfrontinsertion, when the feed-rolls are cast-off, of work-sheets withoutsuch catching, com prising a shield having a fold at its forward edgeand readily insertable between the rear paper-table and the platen toadvance said fold beyond the ends of said fingers, andforwardly-extending clips on said pa per-table to receive and detain therear edge of said shield when the shield is drawn rearwardly to placesaid fold over the forward ends of said fingers to form a smooth forwardedge, said feed-rolls being rendered effective, when desired, topress'said shield towards the platen to hold the work-sheet duringtyping thereon. I

4. In a typewriting machine, a cylindrical platen, a rear paper-tableassociated therewith, a smooth front-insertion shield to be placed onsaid paper-table, and clips at the rear edge of said paper-table topress the rear edge of the shield against the papertable and therebydetain it in fixed position.
